Can you conferm what AFR your running when it seems to be going lean?

30# injectors are not required for a N/A application.

Have you had your Mustang hooked up to a dyno to see where you are leaning out? Do you have a wideband O2 setup? Your car being lean is a sign of something wrong.....

19# injectors are good up to 300 Horsepower

If it's running lean when you get on it my first reaction would be fuel pump, are you still running the stock one? BTW, for your current setup 30# injectors are a bit big, you'd probably do well with 24#.

I'm with the other guys. With 30's you should be rich. It also depends on your fuel pressure. If you don't have an AFPR-get one. If you do, give yourself a little more fp. If that doesn't work try changing the fuel filter. At that point you may want to consider a pump. Also, how do you know that you are running lean?
